DO NOT provide a complete howto here! Instead groom the general HowTos.

Installation

An unconfigured device gets its IP address via DHCP, Login username and password is 'ubnt'. Once the device has been adopted by a controller, it will use the device password of the 'Site config' page. Use ssh to login.

Upgrading OpenWrt

Revert to stock firmware (untested)

You can flash the backup image optionally created before first installation. Note that the configuration partition of the stock firmware is not touched by OpenWrt, so you will also revert to the config used before OpenWrt.

scp your backuped jffs.img to /tmp

ssh into the device

Revert using

mtd write /tmp/jffs.img firmware -r

Also look at the debricking section.

Basic configuration

Specific Configuration

Wifi power

Total gain by antenna and tx amplifier is about 10-11dB, amateurish measured. ath9k doesn't know about this and so doesn't OpenWrt. So if you configure 18dBm transmit power, you'll actually get 28dBm, well outside regulatory limits! For Europe, do not set transmit power beyond 10dBm. As the access points also needs the hear the devices associated to it, one sided transmit power boost would not help with range extension anyway.

Failsafe mode

Use the instructions from → generic.failsafe. The button to trigger failsafe during bootup is the reset button hidden between the two ethernet ports.
